Answer 2

Calculating the Amount of Sunflower Seeds Needed

To calculate the amount of sunflower seeds needed to obtain 2 kg of clean seeds, we can use the given conversion rate.

Given: - 2.5 kg of sunflower yields 1.8 kg of clean seeds

We can use the following formula to calculate the amount of sunflower seeds needed: Amount of sunflower seeds = (Desired amount of clean seeds / Yield from given amount of sunflower seeds) * Given amount of sunflower seeds

Using the given information: Amount of sunflower seeds = (2 kg / 1.8 kg) * 2.5 kg

Calculating the amount of sunflower seeds needed: Amount of sunflower seeds = (2 / 1.8) * 2.5 = 2.7778 kg

Therefore, approximately 2.78 kg of sunflower seeds are needed to obtain 2 kg of clean seeds.
